Supercar Roundup: A New Lamborghini, Audi Snubs the U.S. and Jag Pulls Plug on C-X75

Every so often, automakers do something with their high-horsepower supercars so cool that we have to check out. While chances are slim that most of us will ever get into these six- and seven-figure devices of visceral speed, they're notable for what they bring to the market—or in the case of two of these vehicles, what they don't.
Audi Makes Awesome RS 6 Station Wagon. No, You Can't Have One
If ever you should want a station wagon, this is one of the ones you should pine over. Today, Audi released footage of its 2013 RS 6 Avant, a 560-horsepower, ground-pounding super wagon. Compared to the previous generation, this RS 6 uses a twin-turbocharged 4.0-liter V-8 borrowed from the Audi S8 and Bentley Continental GT instead of a 5.0-liter V-10 from Lamborghini. It's down 20 horsepower from the last model, but it's also shed 220 pounds, helping it scoot to 60 mph in 3.9 seconds—0.7 second quicker than the outgoing model. Power is channeled to all four wheels via a seven-speed dual-clutch gearbox. This is the sort of vehicle your family ought to dream about.
Jaguar Pulls Plug on C-X75 Hybrid Supercar...And You May Be Able to Get One
Without a doubt, we would have loved to see Jaguar's $1 million supercar based on the C-X75 concept go into production. Using a 1.6-liter four-cylinder engine with the help of both superchargers and turbochargers, it would have been able to rev to a motorcycle-like 10,000 rpm, generating as much as 550 horsepower. If that weren't enough, two electric motors were set to power the front wheels, allowing the C-X75 to achieve staggering performance numbers: 0 to 60 mph in under 3 seconds, a more than 200 mph top speed, and a Prius-like 99 grams of CO2 per kilometer emitted.Alas, it's not to be. Jaguar is discontinuing its supercar program in the midst of Europe's financial meltdown. Where it had expected to build 200 to 250 copies of the car, it will now complete development of its five prototypes. Three will be kept by the automaker, with their technology eventually trickling into new products. Two will go up for auction. Happy bidding!
Lamborghini Promises New Supercar Next Year for 50th Anniversary. You Can Have One, Pending Your Check Doesn't Bounce
For its 50th anniversary next year, Automobili Lamborghini has big plans. During the week of the Los Angeles Auto Show, it showed off its Aventador Roadster at a separate event. Yesterday, the automaker said 2013 would be the last year for the Gallardo after a decade run. Long lifespans are typical for Lamborghini models. But for the 50th year of the storied exotic car maker, a new model will bow. Despite Europe and Asia facing some tumult, the Middle East and North America are strong markets for six-figure supercars. Lamborghini is going "full-speed ahead" with its new product plans, unlike Jag with the C-X75.Sources: Audi, Car Magazine, Automotive News (Subscription required)
